Medium Voltage Na2xsy Aluminium Cable

AL/XLPE/CWS/PVC Cable

The NA2XSY （medium voltage）has a single core aluminium stranded class 2 conductor with cross-linked polyethylene (XLPE) insulation, copper wire metallic screen, and polyvinyl chloride (PVC) oversheath. NA2XSY cable is widely used in internal/external power distribution networks,external where it's either direct buried or installed into cable ducting, but also it can be run and terminated inside a building as the NA2XSY cable is flame retardant.

The NA2XSY provides long-term operational reliability due to a low dielectric loss factor and excellent insulation property of XLPE, which makes it widely used in transformer stations, electric power plants and industrial plants. Nevertheless, it should be used in fixed installations to avoid mechanical or tensile strain.
